In a production line, it is possible to work with more than one different production activity. These activities can be setup time, machine time, labor time and may vary according to the needs of the industry. It is important to be able to define different production activities according to the industry and to analyze the actual values ​​of each different activity. Recording the actual values ​​on the basis of activities helps businesses significantly in the analysis of performance and work efficiency.

Different production activities, which are defined in the SAP ERP system and sent to the MII-OEE system via IDoc (Intermediate Document), can be assigned to work units with general configurations on MII. Actual values ​​on the basis of assigned activities can be measured and transferred to the SAP ERP system automatically. In this way, it is aimed to prevent errors that may occur with manual value entry.

Activities can be defined with the following steps, which are within the scope of the PP module, and if there is no need for a new activity, existing defined activities can also be used.

1. SAP ERP Definitions:

Activity Defining in SAP ERP

SPRO-> Production->Basic Data->Work Center->General Data->Standard Value-> Define Parameters

T-Code: OP7B

Activity parameters can be defined via the menu step and the transaction code given above.

Figure 1: Definition of PP parameters (Setup Time)

Figure 2: Definition of PP parameters (Machine Time)

The defined parameters are assigned to the standard value key to be assigned to the work center master data.

SPRO-> Production->Basic Data->Work Center->General Data->Standard Value-> Define the Standard Value Key

T-Code: OP19

Figure 3: Assignment of PP parameters to the standard value key

The relevant work center is created as PP master data on SAP ERP and the determined standard value key is assigned to the relevant field in the basic data.

To create a work center;

SAP Menu->Logistics->Production->Master Data->Work Centers->Work Center->Create

T-Code: CR01

To change the current work center;

SAP Menu->Logistics->Production->Master Data-> Work Centers->Work Center ->Change

T-Code: CR02

To view the current work center;

SAP Menu->Logistics->Production->Master Data-> Work Centers->Work Center -> Display

T-Code: CR03

The specified activities should also be defined in the costing tab of the work center.

Figure 5: Assignment of activities to the work center for costing

At this stage, the record type group should be selected other than “0-Variable service”. Otherwise, the required actual values ​​requested by MII-OEE will not be sent to the SAP ERP system.

In the next step, the activities should also be defined in the OEE menu via SAP ERP. While making this definition, it should be noted that the production activity used in the PP steps and the record type group used in the work center cost calculation tab are defined in the same way in this menu.

SPRO->Production-> Overall Equipment Activity->Define Production Activity

 Data Transfer to SAP MII System via ERP:

The activities created in the SAP ERP system and the work centers to which the activities are assigned should be sent to the SAP MII system via IDoc via SAP ERP.


SAP Menu->Tools->ALE->Master Data Distribution->Logistics->Supply Chain Planning Interface->Production Optimization (POI)->Send Master Data

T-Code: POIM

First, the logical system created for the ERP-MII integration must be defined in the optimization system area. In our example, the logical system is XMIIIDOC01.

Figure 7: Sending work centers to MII system (Logical System)

Then, the work center and plant information are entered and IDoc output is triggered by running the program.

Figure 8: Sending work centers to MII system (Work Center Selection)

Likewise, activities specified as OEE adaptations must also be sended.

SAP Menu->Logistics->Production-> Overall Equipment Effectiveness->Information System->OEE-IDoc Selection

T-Code: /OEE/BO_IDOC

First, the logical system selection must be create.

Figure 9: Sending activities to MII system (Logical System)

Then, the activities to be sent can be selected from the Production Activity field, or if all activities are to be sent, it is sufficient to select the All Production Activities option. In the example below, the IDoc is created only for the SAP_01 activity.

Figure 10: Sending activities to MII system (Activity Selection)

The submitted IDoc details can be accessed as stated below. The status marked with green indicates that the IDocs have been successfully sent from the ERP system.

SAP Menu->Tools->ALE->ALE Administration->Monitoring->IDoc Display-> Display

T-Code: WE02

Figure 11: Monitoring of sended IDoc details

After the IDocs are sent to the SAP MII system via ERP, it should be checked whether they have reached the MII.

2. SAP OEE Definitions:

We can view through queue monitoring that the IDocs we have sent are also recorded on MII-OEE.

Figure 12: Monitoring of sent IDoc details in MII queue

In the next step, the activities must be assigned to the relevant business units in the OEE plant hierarchy. This step is carried out through the general configuration under the worker UI management via the MII menu.

In the image below, the SAP_01 activity is assigned to the Test 1 work center, which is defined on the ERP and sent as IDoc. The configuration is saved after the necessary assignments.

Figure 13: General Configurations

In order for the activity times to be sent to the ERP system when the order is held or completed, the ERP confirmations activity for the relevant work unit must be enabled in the general configurations tab.

Figure 14: General configurations, confirmation at the time of order hold

Figure 15: General configurations, confirmation at the time of order completion

In this way, when the order is held and completed, the automatically calculated times for the selected activity are delivered to the ERP as confirmation.

3. SAP OEE Production Order Activity Selection and Submission to ERP System:

With the OEE dashboard, the order can be started by clicking the Start or Continue buttons for the relevant order via the Manage orders activity. At this point, a pop-up appears on the OEE screen. In this pop-up content, as seen below, the activity to which the work started is determined by selecting the previously defined activity.

Figure 16: OEE order and activity management

When the order is held or completed from the order management screen, the confirmation in the image below will be automatically sent to the ERP system by MII.
